We show that the partial compactification of a stratum of Abelian differentials previously considered by Mirzakhani and Wright is not an algebraic variety. Despite this, we use a combination of algebro‐geometric and other methods to provide a short, unconditional proof of Mirzakhani and Wright's formula for the tangent space to the boundary of a orbit closure, and give new results on the structure of the boundary.

所见即所得的压缩
我们表明,先前由Mirzakhani和Wright考虑的Abelian微分层的部分压实不是代数变体。尽管如此,我们还是结合使用了代数几何和其他方法,以提供一个简短的,无条件的Mirzakhani和Wright公式的正切空间与a的边界的切线的证明。 轨道闭合,并在边界结构上给出新结果。
